What is Inconel 800 and Their Advantages and Uses

Inconel is an excellent example of a high-performance metal that has been specifically designed for some of the most demanding applications. Inconel is not as well-known as steel or aluminum because it is frequently more expensive and less widely used. This article will explain the basics of Inconel and answer some frequently asked questions about this extraordinary metal.

What exactly is Inconel?

Inconel refers to a class of nickel-based super alloys.  In the middle of the twentieth century, the first Inconel alloys were developed for demanding, high-temperature environments.

The Advantages of Using Incoloy 800 Seamless Pipe

The stability of Incoloy 800 Seamless Pipes at high temperatures is one of its advantages. Despite being exposed to high temperatures, this nickel-iron-chromium alloy can maintain its austenitic micro structure. These pipes are annealed for 15 minutes at 1800°F in accordance with ASTM B407 specifications. The Incoloy 800 Seamless Pipe is cooled in air after annealing. Categorization resistance is superior in this alloy. It’s a phenomenon that happens in processing industries when gas mixtures containing hydrocarbons or carbon monoxide come into contact with steel. Cauterization weakens many regular steel grades and reduces their resistance to oxidation and sulfidation due to chromium depletion in the matrix and the formation of carbides on the pipe’s surface.

Inconel’s Molecular Formula

Because Inconel is a group of super alloys rather than a single type of super alloy, its chemical composition varies depending on the alloy type. All Inconel alloys, on the other hand, are nickel-based. Furthermore, chromium is the second most abundant element in the chemical composition of Inconel. Almost every Inconel has some iron in its composition, almost always more than 1%. Other elements found in some Inconel alloys are as follows:





What are the Characteristics of Inconel?

Inconel’s unique combination of physical and chemical characteristics is what makes it so unique. Inconel is well-known for its ability to withstand extreme temperatures. While steel has a higher melting point than nickel, its ability in terms of strength and corrosion resistance starts deteriorating at high temperatures. In contrast, Inconel retains superior mechanical properties at high temperatures and develops a protective oxide coating that withstands corrosion.

Inconel has excellent strength properties at room temperature in addition to its high temperature performance. The high chromium content also provides excellent corrosion resistance at room temperature. Other alloys mentioned in the composition above provide additional properties like toughness and hardness. Precipitation hardening is used to increase the strength of several Inconel alloys, including Inconel 718.

What is the Purpose of Inconel?

Inconel is used in a variety of industries. Inconel is widely used in the aerospace industry, specifically in the elevated environment found within jet engines. Inconel is commonly used to make fuel nozzles, afterburner rings, and other engine components. This is due to their ability to perform well in the high temperatures encountered during operation. They also resist corrosion caused by jet fuel and other liquids. Inconel is also used extensively in rockets and space exploration vehicles In the aerospace industry, two common alloys are Inconel 625 and Inconel 718.

The nuclear industry is another common application for Inconel super alloys. Inconel is commonly used in nuclear reactors because it has high strength, high corrosion resistance, and outstanding high – temperature performance. Two common alloys used in the nuclear industry are Inconel 600 and Inconel 690.

Automotive, manufacturing equipment/tools, oil & gas, firearms, and several other industries use Inconel less frequently. Any application requiring high strength and corrosion resistance in a high temperature environment is a good choice for Inconel use.

Marine Applications of Copper & Nickel

Marine Applications of Copper & Nickel

What is Copper-nickel?

Copper-nickel alloys, also known as cupronickel alloys, are frequently employed in maritime applications due to their strong resistance to seawater corrosion, low macrofouling rates, and superior fabricability.

Copper is strengthened and more resistant to corrosion when nickel is added, and the alloy is still malleable. To improve copper strength, nickel’s corrosion resistance, hardness, weldability, and castability, other elements can be added.

The most popular Copper Nickel 95/5 C70400 Pipes are composed of 90% copper and 10% nickel. It is used in power generating, desalination, offshore oil and gas production, as well as naval and commercial shipping.

Where more resistance to saltwater flow, sand abrasion, wear, and galling, as well as stronger mechanical qualities, are required, alloys with a 30% nickel content (C71500, C71640), as well as those that are more strongly alloyed with aluminum, chromium, or tin, are employed.

Marine Applications of Copper and Nickel

Shipbuilding and Repair: Copper-nickel is used for cooling seawater, bilge and ballast, sanitary, fire fighting, inert gas, hydraulic and pneumatic systems, and chiller systems in shipbuilding and ship repair. Additionally, they can be utilized for feed lines to desalination plants and heating coils in cargo tanks. An interactive diagram of a ship’s systems serves as an example of this.

Difference Between Hastelloy C22 and C276 Tubes

Difference Between Hastelloy C22 and C276 Tubes

What are Hastelloy C22 and C276?


The alloy Hastelloy-C22 is made up of nickel, chromium, and molybdenum. High-temperature reactors and fuel rods are made from it in nuclear power plants. In comparison to Hastelloy-C22, Hastelloy-C276 is a higher grade. Although it has a greater resistance to oxidation than C22, it still maintains ductility and malleability under stress. Although Hastelloy c22 and Hastelloy c276 are both alloy steel tubes, there are some significant distinctions between them that you should be aware of.


Difference Between Hastelloy C22 and C276


In applications where high strength is required, Hastelloy C276 Tubes, a low-alloy, medium-strength alloy, is used. It can be supplied in a round or flat shape and has a carbon concentration of up to 0.0025%. It is perfect for use in various industrial applications, such as nuclear power reactors and chemical processing facilities, due to its service temperature range of -130°C to +300°C.


A better variant of Hastelloy C22 Tubes is Hastelloy C276 because it offers more resistance to cracking than its predecessor. It is even more heat-resistant than the original material thanks to the addition of up to 0.005% carbon, but because its service temperature range is still between -130°C and +230°C, it is not as useful in high temperatures as other materials like carbon steels like austenitic stainless steel 304 or 410 which have higher melting points.


Application of Hastelloy C22 and C276


Metals like Hastelloy c22 and c276 are frequently utilized in the building of tanks, pipes, and other machinery. They are two different steel grades with various characteristics.


Because Hastelloy C22 is a high-strength alloy, it contains more nickel than typical iron-based steel does. It is mostly utilized to create armor plates and other things that must be resistant to extreme pressure or heat. Additionally, it is employed in the production of heat-resistant parts including strainers, valves, and pumps.


Temperatures of Hastelloy C22 and C276 Tubes


High-temperature nickel alloy steels come in two major varieties: Hastelloy C22 and Hastelloy C276. An alloy called Hastelloy C276 is employed in situations where high temperatures are anticipated. It is stronger at high temperatures and has a higher creep resistance than Hastelloy C22. Additionally, it is less brittle than most other alloys and stronger than brass.


When corrosion resistance is needed but high temperatures are not, Hastelloy C22 is employed. Compared to Hastelloy C276 it has less creep resistance, but at room temperature, it has more strength (about twice as much). In contrast to Hastelloy C276, which can only be forged, it is easily machined.

Alloy Steel Plates

Properties and Applications of alloy steel plates

In Alloy Steel Plates, metals are fused using the “alloying” process, which involves the fusion of two or more metals. In most cases, mixing two alloys that are similar is the most common method, followed by heating and cooling. Due to this, the various components of each alloy melt together, giving rise to a brand-new alloy having traits shared by the two others. Alloy steel plates have a good combination of strength, hardness, and toughness.

Alloy steel is a material that is hard and tough and can be used to make heavy components, like gears and engine parts. The alloy steel plates are easy to weld and can be easily machined. The new combinations can create bigger vehicles that require less weight due to their increased strength or light vehicles that require less weight and have more strength as a result of their reduced weight.

Applications of alloy steel plates:

Plates made of alloy steel are employed in numerous applications. These are the most typical applications for alloy Steel:

Structural uses include industrial machinery, roofing, marine structures, and structural beams and columns. Applications for laminate include vehicles, aircraft, and other items that must be impact-resistant.

Surface protection: safeguarding chemicals and other compounds from the elements.

The production of high-alloy steels can be costly, and machining them can be challenging. Due to their hardness, toughness, and corrosion resistance, they can be used to build structural components, automotive components, chemical processing equipment, and power generation equipment.

Properties of alloy steel plate:

Welding works very well with alloy steel plates. You can make lots of items out of these plates, such as buildings, machines, and car parts. There are many excellent qualities of alloy steel that make it a desirable choice for welding:

Excellent surface quality can be found in alloy steel. This ensures that the welds are exceptionally durable and long-lasting. Strong and lightweight, alloy steel has a wide range of applications. This makes it ideal for welding on components that must support the heavy weight (like cars).

It is corrosion and oxidation resistant, so you do not have to worry about your welds failing over time due to water damage or rust.

Creation and processing:

For alloy steel, materials and processing techniques are selected based on their desired outcomes. The appropriate mixture of elements is first fused together for 8 to 12 hours at a temperature of over 1600°C in a furnace. In order to purge impurities from the steel and improve its chemical and physical properties, the steel is then annealed at temperatures above 500°C.

The steel surface with hydrofluoric acid is first cleaned from mill scale (a combination of iron oxides), which are a byproduct of the annealing process before undergoing another round of annealing and descaling. The Alloy Steel Plates are finally melted, molded, and rolled into their final shape.

carbon steel plates supplier

Importance & uses of carbon steel plates

Steel plates can be used in many different industries, depending on their carbon content, which may be low, medium, or high. It can also be broken down by the applications it will be used for. Due to the carbon content in steel, it becomes harder and stronger after heat treatment. However, it also loses ductility, which means that it becomes less bendable and easier to deform. Steel with a high carbon content is difficult to weld, both with and without heat treatment, and as its melting point decreases, it becomes even more difficult to weld.

Manufacturing and processing:

Carbon steel plates can be made from recycled or virgin steel or a mix of the two. Iron ore, coke, and lime are combined in a blast furnace at roughly 1650 °C to produce virgin steel. A carbon-rich material called coke is added to molten iron recovered from iron ore, slag is formed when the remaining impurities have combined with the lime and have risen to the top of the molten metal, where they can be collected, A process known as decarburization is used to lower this carbon content. Once the steel is molten, they contain a carbon content of around 4% by weight.


Low-carbon steel is available in a variety of shapes, including flat sheets, structural beams, and plates. The machining, welding, and cutting of medium carbon steel is more challenging than that of low carbon steel. Hardening and tempering this steel typically entails heat treatment. The carbon tool steel, also known as high carbon steel, is very hard and brittle when it is heated. It is also incredibly difficult to cut, bend, and weld.


Wrought iron is a low-carbon steel plate that has a variety of uses. It’s often used for flat-rolled sheets and strips, shipbuilding, or wire, vehicle bodies, and domestic appliances. It’s widely used for fabrication and paneling because it can’t be altered by heat treatment. Carbon steel plates with the lowest possible amount of carbon are called ‘wrought iron’, used for fencing, gates, and railings, hard but not brittle.

Medium carbon steel is significantly easier to process, and adding moderate amounts of silicon and manganese improves its quality. A center axle, gearbox, shaft, railroad tracks, pipes and couplings, vehicles, refrigerators, and washing machines are all examples of structural steel, commonly called mild steel.

Machining tools, knives, punching, castings, spring, and elevated wire are all made of high carbon steel, which has a substantially higher tensile strength. The high carbon steel that is usually used in cutlery and other metal products is extremely hard and brittle. It can also be used to make water heaters, industrial cast iron, and light poles. Cast iron is also what makes old-fashioned cooking pots.

  • Railings for the feet lifestyle curtain rods for stair railings.
  • Banisters \Shandrails.
  • Curtain rods for showers.
  • Towel racks.
  • Centers for entertainment.

Some limitations to brass tubing:

Because brass tube contains a substantial quantity of zinc, there is always the risk that the metal will show indications of dezincification. The zinc component corrodes during this process, lowering the alloy’s strength. Dezincification happens when the metal is subjected to acidic or alkaline environments with changing pH values. When zinc is removed from copper in brass, it produces a reddish or pinkish residue.

How to clean brass items:

As brass is commonly used as an aesthetic material, it should be carefully cared for even while it is on show basis. Avoid using ammonia-based household cleaners, since the chemical can weaken the brass and cause corrosion cracking. Mild brass polishing chemicals are ideal for this.

What Does Intergranular Corrosion Mean

What Does Intergranular Corrosion Mean

Intergranular corrosion is the type of corrosion that attacks the boundaries of the metal crystallites, as opposed to attacking the surface of the metal. Intergranular Corrosion (IGC) can also be referred to as Intergranular Attack (IGA) under a condition known as grain boundary depletion. It can be defined as an attack along the boundaries of several grains in the metal or near the grain boundary with the largest portion of the grain remaining unaffected. Metals and alloys, like other elements, have micro-structures that can be described as grains. Metals can contain multiple grains, and these are separated by a grain boundary.

Although metal loss is minimal, IGC can cause the catastrophic failure of equipment. IGC is a common form of attack on alloys in the presence of corrosive media that results in the loss of strength and ductility. One should not mistake IGC with stress corrosion cracking (SCC). SCC requires stresses (residual or applied) to act continuously or cyclically in a corrosive environment producing cracks following an intergranular path.

Stainless steels and weld decay sensitization are the best examples of intergranular corrosion. Grain boundaries that are rich in chromium elements will precipitate lead. This makes the boundaries very vulnerable to corrosion attacks in various electrolytes. This is caused by reheating the part that has been welded, especially in multi-pass welding.

In the process of intergranular corrosion, a knife-like attack, a form of intergranular corrosion, can occur when carbon reacts with niobium, titanium or the austenitic stainless steels. Carbides form in the areas close the welded part, making it difficult for them to diffuse. This condition can be corrected by reheating the part to enable the carbides to diffuse.

How Intergranular Corrosion Is Formed

The ICG localized corrosion at grain boundaries is caused by the anodic dissolution of areas weakened by the alloying elements, second phase precipitation or regions with isolated alloying or impurity elements. The remaining part of the exposed surface typically functions as the cathode, and large cathodic areas support the anodic dissolution process.

The cathode to anode ratio is generally greater than one. It depends on factors such as the volume fraction and distribution of electrochemically active phases, the distribution of detrimental alloying and impurity elements, and grain size.

The corrosion rate is dependent on the dominant corrosion mechanism, and factors such as the diffusion of species to or from the anodic front can govern the dissolution kinetics. A significant characteristic of IGC is the development of a relatively homogeneous and uniform depth of attack. The dissolution of grain boundaries causes the dislodging of grains, often referred to as grain dropping. Grain dropping is responsible for most of the weight loss observed after IGC exposure, and corrosion rates can therefore be several orders of magnitude higher than during general corrosion.
